The old lighthouse keeper found the body at dawn today. Inspector Mara Voss arrived quickly and secured the entire crime scene. Blood pooled strangely on the rocks below the tower's base. Three witnesses claimed they heard nothing during the dark night. The victim was a reclusive historian studying local maritime legends. Mara noticed a single brass button near the dead man's hand. Rain began falling softly as she photographed the evidence carefully. The lighthouse keeper seemed nervous and kept wiping his weathered hands. A torn photograph fluttered from the victim's coat pocket sadly. Mara wondered who would kill for forgotten stories and old secrets.
